Are those green knots with tail protostars wrap in gas/dust cocoons or leftovers ?[Green "tadpoles"](http://s3.amazonaws.com/mwp-development/south/0.3x0.15_jpgs/GLM_34870-0083_mosaic_I24M1.jpg "Green "tadpoles"")
This looks like a protostar doesn't it? It seems to be driven away by a much larger region of activity to the left, a nice image, and the first 'green' tadpole i've ever seen 😉
The larger one sure looks like bow shock, implying a body there somewhere. In this scenario the proto star could get starved if the stellar wind is strong enough.
